Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a terminal block for a solenoid valve for connecting the lead wire of a solenoid valve installed in a manifold block and the lead wire of an external power source that supplies power to the solenoid valve. It is something.

[Prior Art] When power is supplied to a solenoid valve installed in a manifold block, the terminal block used to connect the lead wires of the solenoid valve and an external power source is made compact and the lead wires are not cluttered. It is fixed in the manifold in order to

Therefore, when connecting these lead wires to a known terminal block, the wiring must be done in a narrow space within the manifold, which poses a problem in that the wiring requires a lot of effort.

[Problems to be solved by the invention] The purpose of the invention is to create a terminal block for a solenoid valve that is composed of a support block and a terminal block body that is removably attached to the support block, thereby creating a spacious working space. To provide a terminal block that allows connection and removal of lead wires outside the manifold.

[Means for Solving the Problems] In order to achieve the above object, the solenoid valve terminal block of the present invention includes a support base fixed to a manifold block, a support base that is removably attached to the support base, and a terminal block that is installed on the manifold block. The support block has a terminal block body for connecting the lead wire of the solenoid valve and the lead wire from the external power supply, and the support block has protrusions formed opposite to the side edges of both side plates, and a notch in the bottom plate. a notch having an edge, the terminal block main body has a groove in which the protrusion passes through which the side for insertion into the support base is opened on both sides, and a claw that engages with and disengages from the edge of the notch protruding from the main body. The present invention is characterized in that it includes an elastically deformable locking plate having an elastically deformable locking plate.

[Function] Since the terminal block body can be removed from the support base fixed to the manifold block, the work of connecting and disconnecting the solenoid valve and external power supply lead wires to the terminal block body can be done in a manifold with ample work space. It can be done easily, quickly and reliably outside.

The terminal block body to which the lead wire is connected can be attached to the support base with one touch by inserting the groove that is open on the insertion side through the protrusion of the support base. The terminal block main body is stably supported on the support base by the engagement of the claws with the notch edges.

[Embodiment] Hereinafter, an embodiment of the present invention will be described in detail based on the drawings. In FIG. Consisting of a plurality of manifold blocks 2, 2, ... in which flow paths are formed, a pair of terminal blocks 3, 3 that integrate them, and a cover 4 that is attached between the front parts of the terminal blocks 3, 3. Double-acting or single-acting solenoid valves 5 and 6 are mounted on the upper surface of the manifold block 2 to switch the internal fluid flow path. The lead wires 7, 7, . It is configured so that it can be wired.

As shown in FIGS. 1 to 3, the electromagnetic valve terminal block 8 includes a support base 9 fixed to the front surface of the manifold block 2, and a terminal block main body 10 removably attached to the support base 9. It is composed of
As is clear from FIGS. 2 and 3, the support stand 9 is equipped with a back plate 11, a pair of side plates 12, 12, and a bottom plate 13 by sheet metal processing or the like.
The back plate 11 includes a fixed plate portion 11a fixed to the front surface of the manifold block 2 with screws 14,
11a, back plate main body parts 11b, 11b supporting the back surface of the terminal block main body 10, and a lead wire guide plate part 11c bent rearward corresponding to the lead wire guide groove 2a of the manifold block 2. , as shown in FIG. 2, a step is provided between the fixed plate part 11a and the back plate main body part 11b, so that the back plate main body part 11b
and the front of manifold block 2.
5 is formed, and the bottom plate 1 is connected from the guide plate portion 11c through the back plate main body portion 11b.
A notch 16 extending to 3 is formed, and a notch edge 13a is provided on the bottom plate 13, and the side edges of the side plates 12, 12 are curved inwardly to have protrusions facing each other in the longitudinal direction. 12a, 12a are formed.

On the other hand, the terminal block main body 10 is composed of an insulator 17 made of an insulating material such as synthetic resin and lead wire fasteners 18, 18, etc. fixed to the insulator 17. As shown in FIG. 3, the fastening chambers 17a, 17a, .
Grooves 17b, 17b are formed through which the protrusions 12a, 12a are inserted in the insulator 17.
A locking plate 17c, which is inserted into the notch 16 in the support base 9 and can be elastically deformed back and forth, is formed on the back surface of the support base 9. The above notch edge 13a
A claw portion 17d that engages and disengages is formed. Further, the lead wire fastener 18 includes screws 18b for individually fastening the lead wires 7 of the solenoid valves 5 and 6 and the lead wire of an external power source to a metal conduction plate 18a that is integrated into a U-shape. , 18b are screwed into each other.

To use the solenoid valve terminal block with the above configuration, separate the terminal block main body 10 and the support block 9, screw the support block 9 to the manifold block 2, and then move it away from the manifold 1, which has enough work space. At the position shown in FIG.
0 to the support stand 9. When removing or replacing the lead wire from the terminal block main body 10, it is sufficient to remove it by pulling the terminal block main body 10 upward from the support base 9. This can be done easily, quickly and reliably outside where there is sufficient space.

Therefore, in order to attach the terminal block body 10 to the support base 9, the grooves 17b, 17b of the terminal block body 10 and the protrusions 12a, 12 on the side plates 12, 12 of the support base 9 are used.
It is only necessary to move the terminal block body 10 downward while engaging with the terminal block body 10, and as the terminal block body 10 moves downward, the locking plate 17c of the terminal block body 10 slides downward while being accommodated in the notch 16 of the support base 9. The claw portion 17d at the tip eventually hits the notch edge 13a of the bottom plate 13 and protrudes below the bottom plate 13 while being elastically deformed.
d engages with the cutout edge 13a of the bottom plate 13, and the installation of the terminal block main body 10 is completed. In this installed state, the grooves 17b, 17b of the terminal block main body 10 are engaged with the protrusions 12a, 12a of the support base 9, so that displacement of the terminal block main body 10 in the front-rear direction is restricted. At the same time, since the claw portion 17d of the locking plate 17c of the terminal block main body 10 engages with the notch edge 13a of the bottom plate 13, vertical movement of the terminal block main body 10 is restricted, and the terminal block main body 10 is not supported. It is stably attached to the manifold block 2 via the stand 9.

[Effects of the invention] The terminal block for a solenoid valve of the present invention consists of a terminal block main body for connecting the lead wires of the solenoid valve and an external power supply, and a support base fixed to a manifold block, and Since the terminal block body can be attached to and detached from the support base, the above lead wires can be easily, quickly and reliably attached to and detached from the terminal block body outside the manifold, where there is plenty of work space. Since it can be attached and detached with a single touch, the operation is extremely simple and easy.

In addition, by inserting the groove of the terminal block body into the protrusion of the support base and locking the claw of the locking plate to the edge of the notch,
Since the terminal block main body is fixed so as not to move in any direction during installation, the terminal block main body is stably supported.
